I HAD POSTED A SIMILIAR THREAD IN RESTORE AND BACKUP SECTION WHICH I THINK IS NOT AN APPROPRIATE SECTION FOR THIS QUESTION SO POSTING HERE AGAIN WITH MORE DETAILS.

I had this problem last night , my laptop became dead slow at 1st then while browsing it hanged completely and I could not even start task manager , I restarted it by holding the power button and it showed toshiba logo and then a black screen , with blinking cursor, I turned it off after sometime because it was not booting and started looking for the solution. I found the remove battery n charger , hold power for 60sec thing but when I turned it on before applying the method it booted normally now after some hours it became dead slow so I restarted it by going to start > restart and it restarted but again the black screen and white cursor , So after trying 10 times f8 it did not work (win recovery ) I tried the battery removing thing ,still no help, not to forget num lock light is on , fans are working , but i can not do anything else

I ran a bootable kapersky rescue . it showed no virus, then I rebooted it was the same , i rebooted again n the window booted normally with normal super speed as usual, i shut down twice and turn on and it worked, but when I restarted it when to the black screen again n is still the same.
I remember the 1st time when this happened last night was when I restarted it , because it became too slow,
So now I got a point that it is having problem when restarted.


PLEASE SUGGEST ME WHAT TO DO . IS THERE ANY WAY I CAN SIMPLY GOTO THE REPAIR MENU AND REINSTALL THE WINDOW TO SEE IF IT HELPS OR IS THERE ANY AUTO BOOTABLE SOFTWARE WHICH CAN FIND AND FIX THE PROBLEM OR ATLEAST START THE REPAIR WINDOW.
I AM USING Windows 7 HOMEBASIS CAME PRE INSTALLED WITH MY TOSHIBA C660SATELLITE



UPDATE|:


alt + ctrl + del restarts the laptop and nothing else

the blinking dash - r _ in the left top corner blinks no more then 4 times and then nothing happens just black screen
